23. Set Baud Rate Field in Control Register

#include <stdio.h>
#include <stdint.h>

#define BAUD_RATE_MASK 0xFU
#define BAUD_RATE_SHIFT 8U

    // Your code here
    reg &= ~(BAUD_RATE_MASK << BAUD_RATE_SHIFT);
    reg |= ( (uint32_t)(baud & BAUD_RATE_MASK) << BAUD_RATE_SHIFT );

    return reg;

    scanf("%u %hhu", &reg, &baud);
    printf("%u", set_baud_rate(reg, baud));
